I am currently in a very bad crash and have been in bed for months and was thinking to myself- am I at an increased risk for blood clots or DVTs? Why do people who are on planes get DVTs, They are only on a plane for a few hours to many hrs. This also reminds me of when i was in the hospital getting surgery and was completely bed bound and they had to put a compression machine on my legs pronto- i was in the hospital for 2 weeks. But Ive been in bed for months before and currently, and no sign watsoever of DVTs. Should i ask my doctor for a machine or stockings?
